Parmigiano Reggiano Galette Dough

8 oz. unsalted butter, cubed

2 cups all-purpose flour

1/8 cup sugar

1/4 cup Parmigiano Reggiano cheese, finely grated

1/2 teaspoon salt

3 ounces water, cold

Combine butter, cheese, and dry ingredients in the bowl of a food processor, and pulse until the butter is pea-sized or smaller. Pulse the food processor rapidly while adding the water. Do not over-mix.

Turn the dough out onto a length of plastic wrap, and compact it into a flat square 8 x 8 x 1-inch high. Wrap the dough tightly in the plastic and refrigerate for 1 hour before rolling.
